Ben Warren 7194ab8095 Convert SMC91111 Ethernet driver to CONFIG_NET_MULTI API
All in-tree boards that use this controller have CONFIG_NET_MULTI
added
Also:
  - changed CONFIG_DRIVER_SMC91111 to CONFIG_SMC91111
  - cleaned up line lengths
  - modified all boards that override weak function in this driver
  - modified all eeprom standalone apps to work with new driver
  - updated blackfin standalone EEPROM app after testing
